Leners Patent No. 103,908, camz Jim 7, 1s7o.

The Schedule referred to in than Letten Patent and making part of the same.

To all whom it may concern:

.following is a full and exact description of the-same,

reference being had to the accompanying drawing and to the letters of reference marked thereon.

This invention relates tothat class of churns which employ a vertically-moving dasher which is actuated by means of a reciprocating slide operated by gearing, and consists in so arranging the churn in relation to the' frame that supports the gearing, and in so attaching thedasher-rod to the slidefthat the dasher and churn maybe easily detached from the operating mechanism, when desired.

In the drawing@ Figure 1 is a front elevation of my invention, and

Figure 2, a side elevation of'the same.

To enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe fully its construction and method of operation.

A represents an upright churn of the ordinary form, which is provided with the usual dasher and cover a2. B B represent a frame-work resting upon the legs b b b, as show-n.

The part `B consists of the side-pieces b b1, and

cross-pieces.

lThe part B' consists of the endpiece b", crosspieces b4 b4, and perpendicular center beam b5.

The part B is joined to the part B at right angles to it, at about its center, as shown.

C represents a sliding frame, which moves in waysI in the side pieces bl b1.

'lhis frame is provided with a cross-bar c, which, in connectiongvith the lower bar c', forms a slotted opening infjvvhichplays the friction-roller d, on the eccentric-pin d.

E represents a disk or wheel, which is provided with a suitable shaft turning in proper bearings, to which is attached the pin d', as shown in iig. 1. Upon the rear end of the shaft c of the wheel E is located a pinion, e', which gears into thev wheel- F, which latter receives motion from the crank F', as shown. r

H representsa bracketywhich is attached to the lower end of the gate, and is provided witha suitable opening to receive the end of the dasher-rodI, and has also a set-screw by means of whichadj ustment of the latter is permitted, when necessary.

'The operation of rny invention is as follows:

Motion is communicated to the crankll" in any suitable manner, and through it to the wheels F e', and diskE.`

By the revolution of the latter the pind is also caused to revolve. This pin has no eiect upon the frame C in its horizontal movements, as the slotted opening permits it to play freely from side to side, but, when .moving vertically, it necessarily carries the frame C with it, and thus gives it the desired reciprocating movement.

The end of the dasher-rod is. secured in the bracket, and is adjusted at'any suitable height at will.

AIt will be observed that the churn is placed in such relation to the'frame that it can be easily handled and even removed from the latter, if desired, it being only necessary tolo sen the set-screw' which confines the dasher-rod to t 1e slide to sever the connection be tween the two.

By this construction and arrangement, when the- In a churn of thedescribed construction, thebracket H, with its set-screw, when combined with the sliding` frame O and dashersrod I, as described, for the purpose-set forth.

This specitication signed and witnessed this 7th day of September, 1869. f HAMILTON B. MCFALL.
